Save this for when your furnace stops working! 🛠️❄️
Before you assume your heater is broken, there are a few simple things that often cause issues. Checking these first can save you a lot of stress:
1️⃣ The Thermostat: It sounds simple, but make sure it’s actually set to "Heat" and the temperature is higher than the room.
2️⃣ Air Flow: A clogged filter can cause the whole system to shut down for safety.
3️⃣ The Switch: Furnaces have a power switch (it looks like a light switch). Make sure it wasn't accidentally turned off!
Hope this helps you stay warm this winter!
